Now for something a little different!

I found this 1960s vintage transistor amplifier and thought it might be fun to convert to guitar usage.




I couldn't find a schematic or manual, but the ad copy says it runs on 9V DC.  I hooked it up to an 8 ohm speaker and then released some magic smoke







I couldn't locate where the smoke was coming from, but note there is a disc capacitor inbetween the transformers




Please let me know if you might have more information on this little amp!
